求偶是一种精心设计的行为,它传达了动物物种的身份和个体雄性作为配偶的合适性的信息。在果蝇中,有大量的证据表明雌性能够评估和比较雄性求爱,并接受或拒绝雄性作为配偶。这些相对简单的反应最大限度地减少随机性接触,涉及低于标准的同种男性和异性恋男性,并在几代人可以潜在地选择新的身体和行为特征。尽管它在进化和行为上具有重要意义,但人们对涉及交配选择的基因以及在进化过程中如何选择新的雄性和雌性仍然知之甚少。D. simulans和D. sechellia是果蝇的两个最近分化的物种,其中雌性对同种雄性有偏好。在此,我们分析了这两个物种之间的F_2雌性杂交的总数为1,748,发现少数显性基因控制的偏好D。simulans male.我们还绘制了两个冗余的X-连锁位点的交配选择,Macho-XA和Macho-XB,并表明,没有一个是需要女性的吸引力。总之,我们的结果揭示了部分遗传结构,使D。simulans雌虫与D. simulans male.
Courtship is an elaborate behavior that conveys information about the identity of animal species and suitability of individual males as mates. In Drosophila, there is extensive evidence that females are capable of evaluating and comparing male courtships, and accepting or rejecting males as mates. These relatively simple responses minimize random sexual encounters involving subpar conspecific males and heterospecific males, and over generations can potentially select novel physical and behavioral traits. Despite its evolutionary and behavioral significance, little is still known about the genes involved in mating choice and how choices for novel males and females arise during evolution. D. simulans and D. sechellia are two recently diverged species of Drosophila in which females have a preference for conspecific males. Here we analyzed a total of 1,748 F2 hybrid females between these two species and found a small number of dominant genes controlling the preference for D. simulans males. We also mapped two redundant X-linked loci of mating choice, Macho-XA and Macho-XB, and show that neither one is required for female attractiveness. Together, our results reveal part of the genetic architecture that allows D. simulans females to recognize, mate and successfully generate progenies with D. simulans males.
